Abstract: PURPOSE:To prevent a dielectric breakdown at a photoconductive layer of a photoreceptor and a leakage of a bias voltage certainly by covering a protective film of an insulator having an electrically high resistance onto an either surface of a photoreceptor or an electrically conductive belt. CONSTITUTION:A bias voltage having a reversed polarity to a transferring charge is applied to a belt 3 at a time t1 a little before a time tb at which the front end of a transfer paper 7 arrives at a point B. Therefore, the paper 7 is sucked to an electrically conductive belt 3 at the point B and is separated from a photoreceptor 1. But while the bais voltage is applied, the surfaces of the photoreceptor 1 and the belt 3 are directly brought into contact with each other during a time interval from time t1 to time tb. And the dielectric breakdown at the layer of the photoreceptor and the leakage of a bias voltage occure. Then, an insulating protective film 14 having a high electrical resistance is covered onto either surface of a photoreceptor 11 or a belt 14. The photoreceptor is covered with a thin film of a polyester resin and the belt with a silicone resin respectively. Thereby, the dielectric breakdown at a photoconductive layer of the photoreceptor and the leakage of the bias voltage are prevented.
